Abstract :
The TM arrays proposed and experimentally demonstrated in 1960psilas are attractive for the synthesis of low/ultra-low SLLs patterns [1]. As compared to conventional arrays, the TM arrays introduce a fourth dimension, the time, into the design, and the time parameter which can be used to taper the distribution can be easily, rapidly and accurately adjusted. Consequently, it has more flexibility for design and the dynamic-range ratio of the excitation for low/ultra-low SLLs [2]-[3].
